Hi, We are on flink 1.13.3 and trying to upgrade the cluster to 1.14.3 version. I see that job(on 1.13.3) is unable to start up because it says it couldn't find metrics group(inside flinkkafkaconsumer class).
- can I deploy 1.13.3 job on 1.14.3 cluster? - can I deploy 1.14.3 job on 1.13.3 cluster? - How do I upgrade to 1.14.3 cluster without loosing running apps state? I have even tried doing savepoint that did not revive the job. Thank you, Sweta
